Boulder completes construction of $25M investment in drinking water infrastructure

The City of Boulder has reopened south 63rd Street to all travel, marking a significant milestone toward the completion of the 63rd Street Waterline Replacement between CO 119 and Boulder Creek- one of the largest water infrastructure investments in the city's recent history. The $25 million project replaced and upgraded a critical segment of Boulder's drinking water system: nearly 2 miles of waterlines. These large-diameter pipes help move drinking water throughout the city to serve the Boulder community.

Following a successful testing phase, the new pipes are now fully operational, providing safe, clean and high-quality water to both Gunbarrel residents and businesses and elsewhere across the city. This upgrade strengthens the citywide reliability of the entire drinking water network, benefiting the well-being of the entire Boulder community.

"We're pleased to celebrate not just the reopening of a road and multi-use path, but the delivery of a lasting investment that will serve our community's quality of life for decades to come," said Chris Douglass, Utilities Engineering Senior Manager.

While 63rd Street has been temporarily patched with new asphalt, travelers will notice the city has not yet finalized resurfacing of the pavement. Resurfacing will be finished in late spring, pending warmer morning temperatures, which will give the road a finished appearance and provide a smooth driving experience. Work will take place from Twin Lakes Road to just north of Valmont Road at Boulder Creek. Construction will require closing the 63rd Street and Jay Road intersection for up to two days in late spring. All other construction will not require full closures of the street, intersections, or multi-use paths but will involve short-duration traffic controls. Impacts will be posted to Cone Zones.

"With projects of this size, particularly with adjacent construction taking place, we know the work had a major impact on our neighbors and businesses in Gunbarrel and are immensely grateful for their patience."
